Outcome Measures

Primary Outcomes (1)

  • Glomerular Filtration Rate (GFR)

    Absolute change in glomerular filtration rate, GFR, measured by Tc-99m DTPA (diethylenetriamine pentaacetic acid) imaging (Gates Method) in the treated kidney(s) from baseline to during LOTUS

    Baseline and 15 minutes after start of Intervention

Secondary Outcomes (2)

  • Percent change in GFR

    Baseline and 15 minutes after start of Intervention

  • Blood Pressure

    Baseline and 15 minutes after start of Intervention, and 5 minutes after end of intervention

Other Outcomes (2)

  • Cutaneous Injury

    5 minutes after LOTUS intervention

  • Heart rate

    Baseline and 15 minutes after start of Intervention, and 5 minutes after end of intervention.

Study Arms (1)

Low Frequency Therapeutic Ultrasound

EXPERIMENTAL
